Clamp / holder wanted for artists' viewfinder grid

I've recently started figure drawing again, and have a couple of grid viewfinders to help me frame my drawings.

What I need now is something to clamp on to the side of my easel which will hold the grid/card in a fixed place while I draw.

I was wondering if anyone could suggest where I might look?

I'm on eBay at the moment, and it's the sort of thing where every search I do brings back thousands of results from China & the far east…. I could do with having a more specific search term.

It needs some kind of adjustable clamp on one end to fasten onto the edge of my easel, and on the other end, similar, but that can grip something fairly thin like the card of my viewfinder. I guess if the clamp is adjustable enough from thin to wide, both ends could be the same. Whatever connects the two doesn't need to be long but probably needs to be flexible.

Thanks.
